Come on, he thought his father, the African Muslim, served in WWII? It was s slip of the tongue. Now who is his father really? Gramps served in WWII. Gramps raised him. How do we know he didn’t call him Dad? We don’t.

Barry didn’t call Stanley Dunham “grandpa.”
Little Barry did call Stanley Dunham “Pops.”
In fact, there is a cryptic poem the 19-year old Barry wrote called “Pop,” which is about his experience with his supposedly maternal grandfather since Stanley was the only father figure Barry had growing up in the US.
